Performance Comparison of Wireless Routing Protocols In MANETS Using Network Simulator
Abstract
Mobile Ad-hoc Network (MANET) is a collection of mobile nodes forming short lived or temporary networks without having any centralized infrastructure. Mobile nodes join and leave ad-hoc network dynamically. MANET is expected to be very useful for the deployment of temporary networks in emergency situations such as fire, safety, search and rescue operations, meetings or conventions in which people wish to quickly share information. Nodes are the only resource available, which also acts as router to forward packets. Among many, the main challenge of MANET is that of discovering the connections/routes between the mobile nodes within the continuously changing network. Thus routing protocols must be adaptive and fast enough to maintain routes in spite of the changing network topology and low bandwidth. In this paper we have studied and compared the performance of three routing protocols, Destination Sequenced Distance Vector (DSDV), Ad hoc On-demand Distance Vector (AODV) and Dynamic Source Routing (DSR) under different scenarios using Network Simulator (NS2).
